Redirect to specific scene when App is opened from FCM notification in iOS

I know this is an ordinary thing to do in Unity, but I'm not able to find any solution to my problem. Please Help.

Problem: In my application, I want to open the app when the user clicks on a notification and after opening that app I want to open a relevant scene according to the data from a notification. I was able to achieve this functionality in android using androids' Intent class and Unity's AndroidJavaObject & AndroidJavaClass classes. But when it comes to iOS I was not able to find any kind of solution for redirecting the user when the app is opened from a notification.

Here is my code for Android:

 #if UNITY_ANDROID
     if (hasFocus)
     {
         AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
         AndroidJavaObject currentActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");
         AndroidJavaObject intent = currentActivity.Call<AndroidJavaObject>("getIntent");
         string onClickScreen = intent.Call<string>("getStringExtra", "onClickScreen");
         if (onClickScreen != null && onClickScreen.Trim().Length > 0)
         {
             redirectToAppropriateScreen(intent, onClickScreen);
         }
         intent.Call("removeExtra", "onClickScreen");
     }
 #endif
